ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 772,594;- dated October is, 1904;

Application filed February 9,1904.

To all whom it may concern.-

Be it known that I, ROBERT H. WALTER, a citizen of the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented new and useful Improvements in Acetylene-Gas Burners, of which the following'is a specification.

My invention relates to a burner more especially designed to produce heat than light; and the object thereof is to produce an acetylene-gas burner of simple construction that may be used for producing heat. I accomplish this object by the burner described herein and illustrated in the accompanying drawings, in which Figure 1 is a vertical central longitudinal section of my improved burner. Fig. 2 is a plan of the same.

'. In the drawings, A is they mixing-tube, which is provided with the usual air-inlet B in the bottom thereof.

C is the usual spud which supplies the gas to the burner. The mixing-tube opens into an annular supply-chamber D, which is preferably semicircular in cross-section, as shown in Fig. 1. This chamber is preferably cast in two parts and is secured together by bolts E, the top plate being an annular plate provided with burner-tips F. These burner-tips are enlarged in the bottom portion thereof to form a submiXing-chamber G, which is sepa' rated from the general mixing-chamber D by a fine gauze-wire screen H and from the outlet J by a wire-gauze screen I, which prevents back firing into the general mixing-chamber through the outlet of the burner-tip. I have found that a burner in which the general mixing-chamber is five-eighths of an inch across thetop andone-half of an inch deep in the center and the outside diameter is three and onehalf inches and the top plate is provided with eight burner-tips, as shown in the drawings,

whose outlets are one-eighth of an inch and the air-mixing tube is one-half of an inch int5 side diameter, produces satisfactory results.

Serial No. 192,817. (No model.)

These proportions may be Varied within reasonable limits, as will be understood by those skilled in the art.

A burner thus constructed provides a simple and eflicient heat-producingacetylene-gas 5o burner.

Having described my invention, what I claim as new, and desire to secure by Letters said burner-tips having a submixing-chamber in the portion thereof opening .into the supply-chamber and a constricted unobstructed outlet above the submiXing-chamber; wire screening separating said submiXing-chamber from said supply-chamber and said submix ing-chamber from the outlet of said burnertip.

2. In an acetylene-gas burner for producing heat; a burner-tip therefor having a constricted and unobstructed outlet at the top and a submiXing-chamber below said outlet, wire screening at the top and bottom of said submixing-chamber.

3. An acetylene-gas burner comprising a mixing-tube having an air-inlet; an annular supply-chamber into which said mixing-tube opens; burner-tips connected to and opening into said supply-chamber, said burner-tips having outlets at the top and submixing-chambers in the portion thereof opening into the supply-chamber; wire screening at the top and bottom of said submixin'g-chamber.

- In witness that I claim the foregoing I have hereunto subscribed my name this 3d day of February, th

ROBERT H. WALTER.
